I have never had to do a detailed render of a fabric before…I am wondering what the steps are to render fabric as well as leather in PS. I see some nice stuff on here in regards footwear. Is this something that is a standard swatch in PS or Do i have to make it myself?

You should find swatches of similar leather that you want to convey online or in real life, scan them and use them in photoshop. You can colorize the material to whatever suits your purpose. It’s not worth the effort to try to reproduce leather using ps filters, etc.

ditto, I scan all my materials in and save them all in a library ive built up, you just open the material you want resize and change the colour variant.
